SPECIFICATION forming part of Letters Patent No. 334,725, dated January 19, 1886.

Application filed July 6, 1885. Serial No. 170,802. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM H. Srnnon, a citizen of the United States, residing at Losant- Ville, in the county of Randolph and State of Indiana, have invented certain new and useful Improvements in Band-Cutters and Feeders for Thrashing-lliachines; and I do declare the followingto beafull, clear, and exactdescription of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon,whicb form a part of this specification.

My invention relates to means for properly feeding grain to the cylinders of thrashingmachines when the grain is introduced unbound to the feeder; and it consists in certain novel improvements in feeders and band-cutters, as will be fully understood from the following description,whcn taken in connection with the annexed drawings, in which- Figure 1 is a top view. Fig. 2 is a bottom view. Fig. 3is aside elevation. Fig. 4 isa sectional view. Fig. 5 is a perspective view of one of the metal collar-bearings for the shafts of the guard-boards and knives. Fig. 6 is a vertical section through the machine, taken in the planeindicated by dotted lines x :r on Fig. 1. Fig. 7 is a perspective view in detail of a cutter proper and its guard and bar.

Before describing my invention I will state that it is applicable to the well-known thrashing-machines; hence it is not deemed'necessary to either show in the drawings or to describe a thrashing-machine.

Referring. by letter to the accompanying drawings, A designates a horizontal frame, of suitable length, width, and height, which is provided with side boards, A A the latter one of which has an arched passage for allowing the loose grain to be fed to a thrashingcylinder by means of an endless slatted apron, B, which is passed around rollers B 13", whose axes are parallel to the horizontal or longitudinal axis of said cylinder. The apron Bis located beneath the frame A, and at the middle of its length, and it receives rotation in the direction of the arrow on Fig. 1. This motion is transmitted to said apron from a pulley on the shaft of the thrashing-machine cylinder acting through the medium of belts and cone pulleys, of which a is keyed on the shaft b of the roller B, as shown in Fig. 2. In connection with the said cone-pulleys I 5 5 shall use a well-known belt-shifter, by which means the movements of the feeder can be va ried for different kinds of grain.

G O are two endless slatted aprons or carriers, which are passed around rollers and in- 6Q clined toward the middle of the frameApvit-h a space left between them'for discharging the loose grain upon the apron B after the bands have been cut. The lower rollers, c 0, have keyed on their shafts pulleys d d, to which is applied an endless belt, 6. This belt 6 is passed overatightening-pulley, f,and around a driving-pulley, g, which latter receives rotation from the shaft 1) of the roller B by means of bevel spurwheels D D. The tight eningpulleyf for the belt 6 is on the end ofa hand-lever, j", which, after adjustment, can be. rigidly held by a notched arc, f,as shown.

E E are two endwise-movable shafts, which have their end bearings in metal collars F 7 fixed into the side boards, A A, of the frame A. These shafts are arranged over the two endless aprons G 0 near their lower ends, and provided with longitudinally-convex cutters h h,arranged and adapted for severing the bands 83 which bind the bundles of grain. The .said cutter-carrying shafts E Eare also provided with inclined guards i t, which arrest the bundles in their downward movement until their bands are severed,after which the loose :8 grain is allowed to be fed uponlthe apron B and distributed evenly upon it, so as to be properly delivered to a thrashing-machine cylinder.

G G designate two right-angular levers,the 0 vertical axes of which are borne by suitable boxes, jj, secured to one of the side boards, A, of the frame A. One arm ofeach of said levers is slotted, and receives a stud, 7a, which is fixed into the protruding end-of a cutter- 5 carrying bar. The angular lever G has pivoted to one of its arms at in one end of a pitman-rod, H, the opposite end of which is pivoted to a wrist-pin, Z, fixed eccentrically to the face of the belt-pulley d. The angular le- ICO ver G is slotted, and connected to its cuttercarrying bar by a stud, 7t, and this arm is connected by a rod, J, to an arm of the angular lever G at m, as shown in the drawings.

It will be observed that the frame A, with its side boards and inclined endless carriersO O, is at right angles to the direction of travel of the inclined apron B, and that during the descent of the bundles on the aprons O (3 their bands will be severed by the knives h h, and the loose grain will then be distributed evenly upon the apron B, and by it delivered to the thrashing-cylinder. It will also be observed that the inclined belt 0 and oppositely-inclined guard conjointly form a feed-hopper, and that the rectilinear reciprocation of the guard and the convex edge of the knife are to enable it to give a shear cut to the band without changing the width of the opening between the belt and the guard, and by this means the knife helps also to spread the grain by unrolling the sheaf, so to speak,as it passes beneath the guard.

Having described my invention, what I claim 20 I The combination of the inclined traveling endless belt, the oppositely-inclined guard and convex knife attached to the lower edge thereof, and means, substantially as set forth, 25

for imparting rectilinear reciprocation to the knife and guard transversely to the belt, all
